Smelting - an overview | ScienceDirect Topics

For this reason, continuous smelting /converting gas is always diluted with weak process gas (e.g., anode furnace gases) and/or air before it is sent to catalytic SO 2 oxidation. Weaker gases (< 13% SO 2 ) do not need dilution.

Copper Smelting Process - Furnaces Used, By-Products, …

There are several methods of copper smelting, the popular ones being reverberatory smelting and oxygen flash smelting. Both methods require the resultant molten copper to be further processed to achieve a grade of 99.9% pure copper. During the process, the gas given off is converted to sulphuric acid, which can be used in the plant or sold off as a by-product.

The smelting process is continuous. Additional alumina is added to the bath periodically to replace that consumed by reduction. Heat generated by the Additional alumina is added to the bath periodically to replace that consumed by reduction.

Zadra elution circuit - Pyrometallurgy: Roasting, Smelting ...

Not process water. E/W single pass efficiency is critical for Zadra because gold not recovered is then re-circulated back to the elution column, slowing down the elution rate. Eluant flowrate is not too critical in the 2-4 BV/h range. You should be achieving optimum elution with about 30 BV of eluant through the column (15h at 2BV/h). Eluant mix of about 2% caustic and <1% cyanide is typical.

Smelter Plant - PT SMELTING

Smelting Furnace (S-Furnace) Dried concentrate and flux materials like silica sand are injected into S-furnace through vertical lances and oxidized with oxygen-enriched air to produce molten matte and slag, and their mixture overflows from the S-furnace down to the CL-furnace through launder.

The ISACONVERT™ process offers an alternative to batch copper converting operations, such as Peirce-Smith (P-S) converting. It is an attractive option due to its flexibility to treat solid feed and efficiently capture SO2 and reduce in-plant fugitive emissions.

Zinc smelting - Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.
